s/tAML patients were more likely to have a del5/5q (P = 0.01 and P = 0.01, respectively) and a del7/7q (P = 0.05 and P < 0.001, respectively) but less likely to have a core binding factor (CBF) AML (P < 0.001 and P = 0.01, respectively), a normal karyotype (P = 0.05 and P = 0.02, respectively), or a FLT3-ITD (P < 0.001 and P = 0.05, respectively). The gene discussed is FLT3; the disease is acute myeloid leukemia.
